blank lines between import groups is ignored

With a format settings file containing

<setting id="org.eclipse.jdt.core.formatter.blank_lines_between_import_groups" value="1"/>

and java.completion.importOrder specifying groups, all imports are still not spaced.

"java.completion.importOrder": [
        "java",
        "javax",
        "org",
        "com",
        "",
        "#"
    ]

Environment

• Operating System: Linux
• JDK version:
• Visual Studio Code version: 1.76
• Java extension version: 1.15.0

Steps To Reproduce

With

import java.time.Duration;
import java.util.HashSet;
import java.util.Optional;
import java.util.Set;
import java.util.function.Consumer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

2. Format document do not add or remove blank lines

Current Result

import java.time.Duration;
import java.util.HashSet;
import java.util.Optional;
import java.util.Set;
import java.util.function.Consumer;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

Expected Result

import java.time.Duration;
import java.util.HashSet;
import java.util.Optional;
import java.util.Set;
import java.util.function.Consumer;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

Additional Informations

L'issue ne nomme aucun fichier ni test du repository. Reproduisez d'abord le comportement du formatter dans VS Code avec le paramètre fourni du formatter Eclipse, l'ordre des imports et les imports ; le fix est terminé lorsque le formatage insère une ligne vide entre les groupes java et org.
